What does "Good light reflex" mean in a report or doctor's letter? In our medical dictionary, you will find a patient-friendly explanation of the meaning of this medical term.
"Good light reflex" refers to a normal response of the pupils in the eyes when exposed to light. When a light is shone into the eye, the pupil (the black circle in the center of the eye) should become smaller. This is a protective response to prevent too much light from entering the eye. If the pupils respond in this way, it is referred to as a "good light reflex".
